Abstract:
PURPOSE: An aqueous adhesive composition is provided to have superior flame retardancy, and adhesion properties equal or higher than existing oily adhesive, and prevent the contamination of indoor environment during of after works, because of not discharging pollutants according to containing an organic solvent. CONSTITUTION: An aqueous adhesive composition comprises a water-dispersible acrylic copolymer, and one or more hardeners selected from the group consisting of melamine and oxazoline. The water-dispersible acrylic copolymer is the polymer of a monomer mixture, which contains a (meth)acrylic acid ester based monomer, an α,β-unsaturated carboxylic acid-containing monomer, and a flame-retardant component-containing monomer. The amount of the water-dispersible acrylic copolymer is 20-70 parts by weight, and the amount of the hardener is 0.01-5 parts by weight.

Abstract:
A lamination sheet for decoration and a decorative transparent panel with a high cubic effect using the same are provided to form embossed patterns in various sizes, and to keep high adhesive strength even after a photocurable transparent adhesive layer is cured. A multi-layered lamination sheet(10) for decoration has a photocurable transparent adhesive layer(15) capable of being bonded after the adhesive layer is cured. A print pattern layer(12), an emboss pattern layer(13), and the photocurable transparent adhesive layer are laminated on one side of a base sheet(11) in order. The print pattern layer, an adhesive layer(14), and a white sheet are laminated at the back side of the base sheet in order.
