Abstract

The present invention relates to an adhesive for a display and an optical member. The present invention provides an adhesive for a display which has high sensitivity to light, is sufficiently hardenedby low-energy light, and has high hardenability in a portion that is not sufficiently illuminated. The binder for a display of the present invention contains the component (A): a photopolymerizationinitiator represented by the following formula (1); and the component (B): a binder for a display of a photopolymerizable compound; in the formula (1), X a residue obtained by removing n hydrogen atoms from a saturated hydrocarbon having a ring structure, or a substituent represented by the following formula (1-1); when X is a residue obtained by removing n hydrogen atoms from a saturated hydrocarbon having a ring structure; When n represents an integer of 1 to 6, and X is a substituent represented by the formula (1-1), n represents 1. R1 to R7 represent a predetermined substituent; in the formula (1-1), R8 represents an alkylene group or an arylene group; R9 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; and Y represents an oxygen atom or a sulfur atom.

Description

technical field [0001] The present invention relates to an adhesive for displays, and particularly relates to an adhesive for displays containing a photopolymerization initiator and a photopolymerizable compound containing a compound having a specific structure. adhesive adhesive Background technique [0002] The photocurable resin composition is widely used as an encapsulant for electronic components such as an encapsulant for a display, an encapsulant for a solar cell, and an encapsulant for a semiconductor. In terms of specific uses of the encapsulant for displays, for example: sealants or encapsulants for liquid crystals, encapsulants for organic EL displays, and adhesives for touch panels, etc., but in the above applications, it is required to have excellent It has the common characteristics of less outgassing while hardening and no damage to display components. [0003] It is generally known that a photocurable resin composition has an advantage of having excellent c...
