The resistance grazing scar Characteristic hardening die antifogger, use this the resistance grazing scar fog resistance plastic film and the plastic board

摘要

PURPOSE:To obtain the title curing type anti-fogging agent capable of simultaneously providing excellent anti-fogging properties and scratch resistance to the substrate surface of a plastic, etc., by blending a polymerizable monomer or prepolymer with a specific polymerizable polyhydric amine compound. CONSTITUTION:The aimed curing type anti-fogging agent obtained by blending (A) 100pts.wt. polymerizable monomer and/or prepolymer with (B) 10-150pts.wt reaction product of polymerizable polyvalent amine compound such as polyamine (e.g. tetraethylene pentamine) having an acryloyl group or methacryloyl group and =2 primary and/or secondary amino groups in one molecule and (meth) acryloyloxyethyl isocyanate. The anti-fogging agent is applied to a plastic board to form a cured layer.
