FIELD: chemistry.
SUBSTANCE: anti-fogging layers may include an adhesive polymer, a rigid polymer, and a hydrophilic polymer. The adhesive polymer, the rigid polymer and the hydrophilic polymer are different. The hydrophilic polymer is a polymer having a polyurethane backbone. The rigid polymer is a polymer or interpolymer derived from ethylene unsaturated monomers (styrene, styrene derivatives, (meth) acrylic acid or their derivatives, olefins, etc.). The adhesive polymer is a polyester or polyurethane. In additional embodiments, composite materials including a substrate layer; the first adhesive layer; the first transparent layer; the second adhesive layer; the second transparent layer; and an anti-fogging layer are described.
EFFECT: production of coatings and composite materials with enhanced anti-blocking and anti-fogging effects.
