Abstract
Abstract A process for producing a heat-stabilized, shrink-resistant textured master copy for use in producing textured laminates from a textured design model which comprises heat treating the heat and pressure consolidated textured master thermoset copy in an air circulating oven under controlled conditions in order to shrink the copy until it is no longer subject to further significant shrinking or distortion of the surface texture.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
52 words
The process according to claim 1 in which the textured laminated unitary structure has the textured effect imparted thereto by impressing a textured design model into the surface of an assemblage of a stack of thermosetting resin impregnated fibrous paper sheets during the heat and pressure consolidation step in a laminating press.
Claim 2
Dependent Claim
20 words
The process according to claim 1 in which the master copy is heated for about 48 hours at about 135*C.
Claim 3
Dependent Claim
32 words
A process for making a double master copy textured laminated unitary structure comprising bonding a pair of heat stabilized masters prepared according to the process of claim 1 in a back-to-back relationship.
