Thermoset relief patterned sheet. |
摘要 |
<p>The present invention relates to a flexible composite sheet material having a thermoset patterned relief surface of high quality and definition which is particularly useful for producing high quality optical sheet components such as a lenticular screen sheet for producing three-dimensional pictures and photographs. The composite sheet (10) comprises a flexible base film (11) having front and rear surfaces and a layer (12) of a cured thermosetting polymer overlying the front surface of the base film. The cured thermosetting polymer layer has a nonplanar outer surface (13) defining a predetermined desired relief pattern of high quality and durability and of fine definition in the thermosetting polymer layer.</p> |
