Title:

LAMINATE AND TRANSPARENT ELECTRODE FILM

Document Type and Number:

WIPO Patent Application WO/2022/196760

Kind Code:

A1

Abstract:

Provided is a laminate that has excellent optical characteristics and abrasion resistance, has a high yield even when manufactured by a roll-to-roll method, and has excellent OCA adhesion regardless of the presence or absence of annealing treatment. The laminate has a light-transmitting base material layer (A) and a resin layer (B) that is a cured layer of a curable composition (S) containing particles (R) and a curable composition (Q). In a configuration in which the resin layer (B) of 1 μm and PET of 50 μm are laminated to each other, a haze value obtained when the resin layer (B) is measured from an upper-layer side thereof is 2.0% or less. A principal surface (F) of the resin layer (B) on the side opposite to the light-transmitting base material layer (A) has an initial wet tension of 38 to 60 mN/m before annealing treatment. When a heat-resistant protection PET film is affixed to the principal surface (F) and annealing treatment is performed for three hours, the wet tension of the principal surface (F) of the resin layer (B) after the heat-resistant protection PET film is released is 30 to 54 mN/m.
