Title:
OPTICAL LAMINATE
Document Type and Number:
Japanese Patent JP3888710
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain an optical laminate having excellent durability and wet heat resistance in addition to high optical performance by laminating an optical film, a layer produced by copolymerized organohydrosiloxasane and a protective film in this order.
SOLUTION: At least three layers; the optical film A, the layer B produced from the copolymerized organohydrosiloxasane and the protective film C are laminated in this order. Namely, the layers B formed by subjecting the copolymerized organohydrcsiloxasane to a heat treatment and humidification treatment are disposed in at least ≥1 layers between the optical film A and the protective film C consisting of cellulose triacetate, etc. The optical film A, the layer B and the protective film C suffice if these films and layers are laminated in order of the optical film A/the layer B/the protective film C. Layers of adhesives, etc., may be arbitrarily interposed between the respective layers. There is not always a need for forming the layer B if the optical film A and the protective film C are laminated by using a soln. consisting of the copolymerized organohydrosiloxasane as the adhesive and subjecting the films to the heat and humidification treatments.
