<P>PROBLEM TO BE SOLVED: To provide a laminate, in which a triacetyl cellulose substrate and a polarizing plate are laminated via a pressure-sensitive adhesive layer and shrinkage stress of the triacetyl cellulose substrate may be relaxed without using a peroxide even under high-temperature and high-humidity when a glass substrate is further laminated on a surface of the polarizing plate, and which can prevent a pressure sensitive adhesive film of the TAC substrate from being floated from an adherend. <P>SOLUTION: In this laminate, a pressure-sensitive adhesive layer 12 is formed on a triacetyl cellulose substrate 11. The pressure-sensitive adhesive layer 12 includes an acrylic pressure-sensitive adhesive, an isocyanate curing agent, and an acrylic copolymer, wherein tanδ(60°C)/tanδ(20°C) being a ratio of a loss tangent of the pressure-sensitive adhesive layer 12 at 60°C to the loss tangent at 20°C is 1.1 or more and less than 1.3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
