Transparent pressure-sensitive adhesive product for optical use, transparent pressure-sensitive adhesive laminate for optical use and manufacturing method thereof

A method for manufacturing the transparent pressure-sensitive adhesive laminate for optical use, the method comprising:

• a molding step of supplying an uncured liquid addition reaction-type silicone gel starting material onto a release film (B), and setting the thickness of the material;
• a heating step of heating and curing, while in contact with air, at least part of the surface of the uncured silicone gel starting material that is not in contact with the release film (B), after molding or simultaneously with molding;
• a cooling step of cooling the cured silicone gel obtained in said heating and curing step, together with the release film (B);
• and
• a release film affixing step of affixing a release film (A) to the face heated and cured in contact with air in said heating step.

• a cooling step of cooling the cured silicone gel obtained in said heating and curing step, together with the release film (B);
• and
• a winding step of winding the release film (B), with the adhesive face (a) formed by curing in contact with air in said heating step being in contact with the rear face of the release film (B).

A method for manufacturing the transparent pressure-sensitive adhesive laminate for optical use, the method comprising:

• a molding step of sandwiching an uncured liquid addition reaction-type silicone gel starting material between a release film (A) and a release film (B), and setting the thickness of the material;
• a heating step of heating and curing, after molding or simultaneously with molding;
• a cooling step of cooling the cured silicone gel obtained in said heating and curing step, together with the release film (A) and the release film (B);
• a peeling step of peeling the release film (A) off the cured silicone gel and exposing the adhesive face (a);
• and
• a winding step of winding to a roll shape together with the release film (B), with the adhesive face (a) in contact with the rear face of the release film (B).
