Abstract
Abstract A method as disclosed for preventing the formation of Newton ring light patterns between a transparency or photographic negative and a transparent mounting surface such as a sheet of glass. The method comprises the application of a thin film of a substantially transparent resin to form a matte surface finish on the surface of the transparency to be applied against the mounting surface and then mounting the transparency or equivalent to the mounting surface with the resin film interposed therebetween, such that the matte resin film serves as a spacer and also reduces reflection of light between the transparency surface and the mounting surface.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
94 words
A method for preventing the formation of Newton ring light patterns between a transparency or the like and a transparent mounting surface, said method comprising the steps of: applying a thin film of a substantially transparent resin to form a matte surface finish on the surface of said transparency to be applied against said mounting surface; and mounting said transparency to said mounting surface with said resin film interposed therebetween, such that said matte resin film serves as a spacer and also reduces reflection of light between said transparency surface and said mounting surface.
Claim 2
Independent Claim
94 words
A method for preventing the formation of Newton ring light patterns between a transparency or the like and a transparent mounting surface, said method comprising the steps of: applying a thin film of a substantially transparent resin to form a matte surface finish on the surface of said transparency to be applied against said mounting surface; and mounting said transparency to said mounting surface with said resin film interposed therebetween, such that said matte resin film serves as a spacer and also reduces reflection of light between said transparency surface and said mounting surface.
Claim 3
Dependent Claim
60 words
The method of claim 1 wherein said step of applying further comprises the steps of: applying a resinous solution on the surface of the transparency to be applied against the outer surface of the transparent mounting surface; and allowing the resinous solution to dry so as to form a thin resin film having a matte finish over the transparency surface.
Claim 4
Dependent Claim
18 words
The method of claim 2 wherein said step of applying comprises the step of spraying said resinous solution.
Claim 5
Dependent Claim
40 words
The method of claim 2 or claim 3 wherein said resinous solution comprises a resin substantially transparent to light dissolved in a solvent system selected for low surface tension to obtain good wetting of a surface sprayed with said solution.
Claim 6
Dependent Claim
20 words
The method of claim 4 wherein said resin is of the type used in commercially available hair setting spray preparations.
Claim 7
Dependent Claim
20 words
The method of claim 3 wherein said resin is of the type used in commercially available hair setting spray preparations.
Claim 8
Independent Claim
124 words
A method for preventing the formation of Newton ring light patterns between a transparency or the like and a transparent mounting surface, said method comprising the steps of: spraying a resinous solution on the surface of the transparency to be applied against the transparent mounting surface, said solution comprising a resin substantially transparent to light dissolved in a solvent system selected for low surface tension to obtain good wetting of a surface sprayed with said solution; and allowing the sprayed resinous solution to dry so as to form a thin resin film having a matte finish over the transparency surface, such that said matte resin film serves as a spacer and also reduces reflection of light between said transparency surface and said mounting surface.
Claim 9
Independent Claim
124 words
A method for preventing the formation of Newton ring light patterns between a transparency or the like and a transparent mounting surface, said method comprising the steps of: spraying a resinous solution on the surface of the transparency to be applied against the transparent mounting surface, said solution comprising a resin substantially transparent to light dissolved in a solvent system selected for low surface tension to obtain good wetting of a surface sprayed with said solution; and allowing the sprayed resinous solution to dry so as to form a thin resin film having a matte finish over the transparency surface, such that said matte resin film serves as a spacer and also reduces reflection of light between said transparency surface and said mounting surface.
Claim 10
Dependent Claim
20 words
The method of claim 7 wherein said resin is of the type used in commercially available hair setting spray preparations.
Claim 11
Dependent Claim
20 words
The method of claim 1 wherein said resin is of the type used in commercially available hair setting spray preparations.
