Patent Searching and Data


Title:
接着フィルムおよびその利用
Document Type and Number:
Japanese Patent JP4625458
Kind Code:
B2
Abstract:
Disclosed in an adhesive film which enables to obtain a flexible metal clad laminate which is suppressed in dimensional change when produced by heat roll lamination. Such an adhesive film comprises a heat-resistant layer containing a highly heat resistant polyimide and an adhesive layer which is formed on at least one surface of the heat-resistant layer and contains a thermoplastic polyimide. In this adhesive film, the thermal shrinkage ratio in the TD direction is not less than +0.01%, and the thermal shrinkage ratio in the MD direction is not more than −0.02%. Consequently, when a metal layer and the adhesive film are bonded together by heat roll lamination and the resulting laminate is subjected to a treatment with heating, occurrence of dimensional changes can be sufficiently suppressed.
