Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
34 words
The process as claimed in claim 1 wherein the temporary top layer consists of a member selected from the group consisting of polyethylene, polyvinylchloride, polyvinylfluoride, polyester, polytetrafluoroethylene, and metal sheet materials, films or foils.
Claim 2
Dependent Claim
41 words
The process of claim 1 wherein a mold-release agent for facilitating stripping of the temporary top layer material after the coating has been hardened is provided between the surface of the coating layer and the material of the temporary top layer.
Claim 3
Dependent Claim
48 words
The process of claim 1 wherein the temporary top layer consists of a mold release agent for facilitating stripping of the temporary top layer material after the coating has been hardened which is in the form of a thin film or mold-release paper and a suitable backing material.
Claim 4
Dependent Claim
33 words
The process of claim 4 wherein the surface of the mold-release agent in contact with the surface of the coating is provided with the mirror image of the desired surface texture and finish.
Claim 5
Dependent Claim
19 words
The process as claimed in claim 1 wherein the coating material in its hardened condition is transparent or translucent.
Claim 6
Dependent Claim
48 words
the process as claimed in claim 1 wherein the surface of the temporary top layer in contact with the coating is arranged in a defined, given distance from the original surface of the uncoated article this way producing a coating layer of a specified and closely controlled thickness.
Claim 7
Dependent Claim
17 words
The process as claimed in claim 1 wherein the original surface is encapsulated by the coating layer.
Claim 8
Dependent Claim
26 words
The process as claimed in claim 8 wherein the coating layer is of a thickness sufficient to produce a plane surface on a relief pattern surface.
Claim 9
Dependent Claim
48 words
The process as claimed in claim 1 wherein the article to be coated possesses the form of flat sheets or a band and the coating, application of the temporary top layer, hardening of the coating and removal of the temporary top layer is performed on a continuous basis.
Claim 10
Dependent Claim
142 words
A process for the manufacture of printed circuits comprising producing a first or a first and a second circuit conductor pattern adhered to the surface or surfaces of a suitable base member; coating the surface or selected portions of the surface with a layer of viscous, liquid, unpolymerized composition hardenable by polymerization or cross-linking; bringing the surface of the said coating layer into temporary contact with the surface of a material not adhering to the coating in its hardened condition and possessing the surface texture desired for the coating layer to form a temporary top layer, said material of the top layer being arranged in such defined distance from the surface of the base member to produce a coating layer having a plane surface; hardening the coating material by polymerization or cross-linking; and removing the temporary top layer from the hardened surface.
Claim 11
Dependent Claim
161 words
A process for the manufacture of nameplates, dials, decorative sheet material and the like comprising producing on the surface of a suitable material a desired imprint, surface image, relief or pattern, coating the surface or selected portions of the said surface with a coating consisting of a viscous, liquid, unpolymerized composition hardenable by polymerization or cross-linking; bringing the surface of the said layer into the close contact with the surface of a material not adhering to the coating in its hardened condition and having its surface in contact with the coating provided with the mirror image of the surface finish and texture specified for the finished product, providing for a distance between the surface of the coating and the said material forming the temporary top layer adequate for producing a coating layer of specified thickness and sufficient to fully encapsulate the original surface; hardening the coating material by polymerization or cross-linking; and removing the temporary top layer from the hardened surface.
