PHOTOCURABLE PSEUDOADHESIVE AND INFORMATION LAMINATE PREPARED BY USING THE SAME

Japanese Patent JP3037668

B2

PROBLEM TO BE SOLVED: To provide a pseudoadhesive compsn. which, when applied to the surface of a sheet and cured, forms a coated surface which has a good slipperiness, does not exhibit blocking, provides a high-gloss printed surface after peeling, and can further enhance printing effects by incorporating a specific polyurethane (meth)acrylate oligomer and a photopolymn. initiator into the pseudoadhesive so that the resulting compsn. has specified physical properties.
SOLUTION: This pseudoadhesive compsn. contains a polyurethane (meth) acrylate oligomer prepd. by the reaction of (A) a polyisocyanate, (B) a polyol, and (C) a hydroxylated (meth)acrylate and (D) a photopolymn. initiator. If necessary, the compsn. may further contain a lubricant, a fine powder, a polyisocyanate, and one or more silane coupling agents. The compsn. is applied to the surface of paper or a sheet such as of a plastic and is cured by the exposure to light to form a cured film. Thus formed film is required to have a glass transition temp. of 40°C or lower and a loss modulus becoming lower than 107 Pa at 80°C or lower.
