<p>PROBLEM TO BE SOLVED: To clarify printing, to create a sense of high grade and to improve contact feeling and interlayer peeling strength by setting ray transmittance of a polyester and rubber composite film to a specific numeric value range, and setting an interlayer peeling strength of the polyester film and rubber film to a specific numeric value or more. SOLUTION: As a rubber film complexed with a polyester film, a silicone rubber or a polyurethane rubber is better in view of improvement in contact feeling. The silicone rubber having high transparency as a silicone rubber compound is satisfactorily used, and as the polyurethane rubber, both thermoplastic type and crosslinking type may be used. An arbitrary character or design is printed on an opposite side of a rubber film laminated surface, the rubber film side is used as a front surface, and assembled as a component in an equipment. Thus, light transmittance of the polyester and rubber composite film for developing the contact feeling improving effect is satisfactorily 85 to 97%, and an interlayer peeling strength of the polyester film and the rubber film is satisfactorily 4N/20mm or more.</p> |
