| 摘要 |
A photopolymer blend or system is disclosed capable of deposition onto a substrate (such as fabric, paper, plastics, metal or wood) to form text, drawings or shapes by a printing method such as by stencil printing or inkjet printing and capable of polymerisation to form a solid, light transmitting material having volume refractiveindex variations or surface relief features by the exposure of the deposits of the blend to electromagneticor other radiation. The blend includes a monomer, prepolymer, macromonomer or co-monomer comprising silicone groups, and at least one component of the system incorporates ethylenic unsaturation such that the system is capable of undergoing free radical initiated polymerisation. The blend or mixture may also contain various combination of thixotropic agents, and/or thickeners and/or dyes or pigments. |
