Abstract
Abstract A decorative panel having areas of different light reflecting characteristics is manufactured by inhibiting the curing of selected areas of a resinous top coat material which is applied to a panel substrate. In one technique a curing inhibitor is applied to selected areas of the substrate surface prior to application, over the entire surface, of a top coat material containing a mixture of an alkyd resin with melamine-formaldehyde, urea-formaldehyde or a mixture thereof. Upon curing, the inhibitor treated areas cure more slowly than the untreated areas and are characterized by a roughened, diffusely reflecting surface contrasting with the untreated areas having a smooth reflecting surface.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
162 words
A method of making a panel having a substantially flat planar surface with areas of differing light reflection characteristics, comprising the steps of: applying to substantially the entire surface of a panel substrate a uniform thickness of a curable resinous top coat material comprising an alkyd resin and a second resin selected from the group consisting of urea-formaldehyde, melamine-formaldehyde and a mixture of urea-formaldehyde and melamine-formaldehyde wherein the ratio of alkyd resin to the second resin is in the weight ratio range of 1:19 to 19:1. Curing said top coat material over substantially the entire surface thereof; and inhibiting the curing of said top coat material in portions overlying selected areas of said surface to cause said portions to cure at a lower rate than the remainder of the coating thereby obtaining a cured substantially flat and planar top coat surface which reflects light more diffusely in a desired microscopically roughened pattern corresponding to the inhibited portions of said top coat material.
Claim 2
Independent Claim
162 words
A method of making a panel having a substantially flat planar surface with areas of differing light reflection characteristics, comprising the steps of: applying to substantially the entire surface of a panel substrate a uniform thickness of a curable resinous top coat material comprising an alkyd resin and a second resin selected from the group consisting of urea-formaldehyde, melamine-formaldehyde and a mixture of urea-formaldehyde and melamine-formaldehyde wherein the ratio of alkyd resin to the second resin is in the weight ratio range of 1:19 to 19:1. Curing said top coat material over substantially the entire surface thereof; and inhibiting the curing of said top coat material in portions overlying selected areas of said surface to cause said portions to cure at a lower rate than the remainder of the coating thereby obtaining a cured substantially flat and planar top coat surface which reflects light more diffusely in a desired microscopically roughened pattern corresponding to the inhibited portions of said top coat material.
Claim 3
Dependent Claim
28 words
The method of claim 1 wherein said inhibiting step is carried out by applying a curing inhibitor to said selected areas prior to applying said top coat material.
Claim 4
Dependent Claim
11 words
The method of claim 2 wherein said curing step comprises heating.
Claim 5
Dependent Claim
26 words
The method of claim 3 wherein said curing inhibitor is applied to said substrate surface in said selected areas prior to applying said top coat material.
Claim 6
Dependent Claim
25 words
The method of claim 4, further comprising applying said curing inhibitor in said selected areas by printing a coating containing inhibitor on said substrate surface.
Claim 7
Independent Claim
186 words
A method of making a substantially flat panel having more than one gloss for reflecting light in a desired pattern, which comprises: applying to a panel substrate, in a desired pattern, a a solution containing a curing inhibitor for a subsequently applied resinous top coat, coating substantially the entire surface of the patterned substrate with a uniform thickness of a curable resinous top coat material comprising an alkyd resin and a second resin selected from the group consisting of urea-formaldehyde, melamine-formaldehyde and a mixture of urea-formaldehyde and melamine-formaldehyde wherein the ratio of alkyd resin to the second resin is in the weight ratio range of 1:19 to 19:1; heating the coated substrate to cure the top coat over substantially the entire surface thereof such that the top coat overlying the pattern of curing inhibitor cures at a lower rate than the top coat not overlying the pattern of curing inhibitor to provide a top coat with a substantially flat and planar surface having a microscopically roughened pattern thereon causing light to be reflected more diffusely from said pattern corresponding to the pattern of curing inhibitor applied.
Claim 8
Independent Claim
186 words
A method of making a substantially flat panel having more than one gloss for reflecting light in a desired pattern, which comprises: applying to a panel substrate, in a desired pattern, a a solution containing a curing inhibitor for a subsequently applied resinous top coat, coating substantially the entire surface of the patterned substrate with a uniform thickness of a curable resinous top coat material comprising an alkyd resin and a second resin selected from the group consisting of urea-formaldehyde, melamine-formaldehyde and a mixture of urea-formaldehyde and melamine-formaldehyde wherein the ratio of alkyd resin to the second resin is in the weight ratio range of 1:19 to 19:1; heating the coated substrate to cure the top coat over substantially the entire surface thereof such that the top coat overlying the pattern of curing inhibitor cures at a lower rate than the top coat not overlying the pattern of curing inhibitor to provide a top coat with a substantially flat and planar surface having a microscopically roughened pattern thereon causing light to be reflected more diffusely from said pattern corresponding to the pattern of curing inhibitor applied.
Claim 9
Dependent Claim
40 words
A method as defined by claim 6 further comprising: coating said surface with a resinous ground coat prior to applying said curing inhibitor wherein said ground coat is not substantially softened by said solution of the top coat curing inhibitor.
Claim 10
Dependent Claim
26 words
A method as defined by claim 7 wherein the solution containing a top coat curing inhibitor contains about 7 to 30% by weight of said inhibitor.
Claim 11
Dependent Claim
30 words
A method as defined by claim 8 wherein the top coat curing inhibitor is selected from the group consisting of an amino methyl propanol, a hydroxyethyl-trimethyl ammonium bicarbonate, and choline.
Claim 12
Dependent Claim
18 words
A method as defined by claim 7 wherein the curing inhibitor comprises 15% by weight of said solution.
