In the case where the cured product of the curable adhesive for a polarizing film of the present invention is immersed in pure water of 23 ° C for 24 hours, the overall water absorption ratio represented by the following formula is used. 10% by weight or less, that is, the overall water absorption rate (%) = formula: {(M2-M1) / M1} × 100 (%)n{However, in the above formula, M1 represents the weight of the cured product before impregnation, and M2 represents the weight of the cured product after impregnation}. The hardening type adhesive for the polarizing film is excellent in adhesion between the polarizing member and the transparent protective film, and can satisfy optical durability in a severe environment under high temperature and high humidity, and even when immersed in water for a long time, It also has sufficient support. |
