OPTICAL RECORDING CARRIER PROVIDE WITH AN URETHANE ACRYLATE ADHESIVE LAYER

摘要

The inventive optical recording carrier (1) consists of a first assembly (A) comprising at least one carrier layer (2) which is provided with a path (3) and an active layer (4) which is deformable by a thermal stress action and of a second assembly (B) comprising at least one protective layer (7). Said second assembly (B) is fixed to the active layer (4) of the first assembly (A) by means of a deformable adhesive layer in the form of a urethane acrylate adhesive layer (10). Said urethane acrylate adhesive is advantageously selected in such a way that the glass transition temperature thereof ranges from 50 to 10 °C and the thickness of the urethane acrylate adhesive layer (10) is preferably ranges from 5?m to 100?m, more particularly, from 10?m to 50?m.
