The present invention is to provide an adhesive agent composition, including: a main agent containing a polyether polyurethane polyol and a bisphenol A-type epoxy resin; and a curing agent, wherein the polyether polyurethane polyol is obtained by reacting a polyalkylene glycol including repeating units each having a carbon number of 3 or 4 and an alkane diol monomer with an organic diisocyanate at an equivalent ratio (NCO/OH) of 0.7 or more but less than 1, a weight average molecular weight thereof is in the range of 20,000 to 70,000, and an urethane bond equivalent thereof is in the range of 320 to 600 g/eq, and wherein a number average molecular weight of the bisphenol A-type epoxy resin is in the range of 400 to 5,000, and the bisphenol A-type epoxy resin is of a solid state or a semisolid state at normal temperature.

Adhesive agent composition and laminated body

The present invention relates to recording material having a laser coloring layer, wherein the laser coloring layer comprises one or more materials selected from among pigments, dyes and inorganic materials, and the laser coloring layer exhibits absorption at a wavelength within a range from 700 to 12,000 nm. The recording material of the present invention has a laser coloring layer of a desired hue, such as yellow, cyan, magenta, orange, white or black, and by conducting printing by laser irradiation, a recorded item with excellent color tone can be obtained.

Recording material and method of recording

The present invention provides a decorative paper which is excellent in solvent resistance, and chemical resistances such as alkali resistance, acid resistance and alcohol resistance without carrying out complicated steps such as an addition of a curing agent into a ink layer because the ink layer which is poor at solvent resistance and chemical resistance is crosslinked. The decorative sheet of the present invention comprises a base material, an ink layer, a curable primer layer containing a curing agent reactive with a resin in the ink layer, and an active energy ray-curable surface protective layer, which are provided in the order of the curable primer layer/ink layer/active energy ray-curable surface protective layer on the base material.
