Abstract

Abstract There is provided a method of applying transfers or decalcomanias to a tacky surface particularly the surface of a partially cured fiber glass article. The transfer decalcomania includes a backing sheet, a first intermediate layer applied to the backing sheet and a design layer, with or without a second intermediate layer interposed between the first intermediate layer and the design layer. Where a second intermediate layer is not included, the first intermediate layer is such that the adhesion between it and the design layer is less than the adhesion between the first intermediate layer and the backing sheet and between the design layer and a tacky surface. Where a second intermediate layer is included, the adhesion between the said first and second layers is less than the adhesion respectively between the first intermediate layer and the backing sheet, the second intermediate layer and the design layer and the design layer and a tacky surface. The transfer may be applied to an initial resin coat applied to the inside of a mould after which the fiber glass article is completed by additional layers of fiber glass and resin whereby the design is embedded in the article and can be seen from the outside.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 25 words
A method as claimed in claim 1 wherein the transfer includes a pigmented resin layer interposed between said first intermediate layer and said design layer.
Claim 2
Dependent Claim 84 words
A method as claimed in claim 1 wherein the transfer includes a second intermediate protective layer interposed between said first intermediate layer and said design layer, said second intermediate layer being so selected that the adhesion between said first and second intermediate layers is less than the adhesion respectively between said first intermediate layer and and backing sheet, said second intermediate layer and said design layer and between said design layer and the partly cured resin surface to which said design layer is applied.
Claim 3
Dependent Claim 19 words
A method as claimed in claim 3 wherein the second intermediate layer of the transfer comprises a pigmented layer.
Claim 4
Dependent Claim 21 words
A method as claimed in claim 3 wherein the second intermediate layer of said transfer is formed of a cellulose derivative.
Claim 5
Dependent Claim 31 words
A method as claimed in claim 3 wherein the second intermediate layer is applied to said first intermediate layer in the form of a solution of cellulose nitrate in butyl lactate.
Claim 6
Dependent Claim 25 words
A method as claimed in claim 1 wherein the first intermediate layer comprises a silicone applied to at least one surface of the backing sheet.
Claim 7
Dependent Claim 18 words
A method as claimed in claim 1 wherein the first intermediate layer of said transfer consists of polythene.
Claim 8
Dependent Claim 34 words
A method as claimed in claim 1 wherein the design layer applied to said partly cured resin surface comprises 13.2 wt.% nitrocellulose, 64.2 wt.% amyl lactate, 3.6 wt.% dioctylphthalate and 19.0 wt.% of pigment.
Claim 9
Dependent Claim 34 words
A method as claimed in claim 1 wherein the design layer applied to said partly cured resin surface comprises 24.5 wt.% polybutyl methacrylate, 62.0 wt.% xylene, 1.3 wt% phthalyl-glycolate and 12.2 wt.% of pigment.
Claim 10
Independent Claim 142 words
A method of applying a design to a resin-bonded fiber glass body during the manufacture of said body which consists in applying a transfer comprising a backing sheet, a first intermediate release layer applied to said sheet, a second intermediate layer applied to said first intermediate layer, a design layer applied to said second intermediate layer and a layer of adhesive selected from modified esters of an acrylic acid applied to at least those areas of said second intermediate layer which remain exposed after said design layer has been applied to said second intermediate layer, to a resin surface of said body with the design layer in contact with said resin surface, stripping said first intermediate release layer and backing sheet from said second intermediate layer and applying at least one further layer of the bonding resin to said second intermediate layer.
