To provide a non-silicone-based releasing agent composition providing a release sheet having good release property to an uncured polyimide-based adhesive layer, a release sheet for polyimide-based adhesive and an adhesive laminate.
The releasing agent composition comprises (A) an alkyd resin and (B) a melamine resin having average 0.1-2 (based on a triazine nucleus) primary and/secondary amino groups in (70:30) to (10:90) weight ratio based on solid content and the composition is used for formation of a releasing agent layer in a release sheet to which a polyimide-based adhesive is applied. The release sheet for polyimide-based adhesive is obtained by providing the releasing agent layer composed of the composition on a substrate. The adhesive laminate is obtained by providing an uncured layer composed of the polyimide-based adhesive on the releasing agent layer of the release sheet.
