Problems solved by technology

[0007] However, there are problems in that the scratch resistance and chemical resistance of the coating layer formed by the above-mentioned hydrophilic coating agent are poor, and furthermore, it takes time to cure the above-mentioned hydrophilic coating agent, so the productivity is low.
[0009] However, there are problems in that the scratch resistance and tensile elongation of the coating layer formed from the above-mentioned oily and easy-cleaning resin composition are poor, and furthermore, it takes tim...

Abstract

The present invention provides a two-pack type curable coating agent which is capable of forming a coating layer that has excellent transparency, hardness, scratch resistance, oil wiping-off properties and tensile elongation. A two-pack type curable coating agent of the present invention is characterized by containing: a base material which contains 100 parts by weight of an acrylic polymer that comprises a photopolymerizable group and a hydroxyl group in side chains and has a hydroxyl number of 30-350 mgKOH/g and a weight average molecular weight (Mw) of 5,000-200,000, 0.3-35 parts by weight of a silane coupling agent, 0.3-35 parts by weight of a polyether polyol, 3-70 parts by weight of a polylactone polyol and 6-500 parts by weight of a photopolymerizable polyfunctional compound that comprises two or more photopolymerizable groups in each molecule; and 3-100 parts by weight of a curing agent which contains a polyisocyanate.

Description

technical field [0001] The present invention relates to a two-component curing type coating agent, and specifically relates to a two-component curing type coating agent for forming a coating layer for coating the surface of members used in various industrial fields. Background technique [0002] Conventionally, various optical members such as touch panels, displays, lenses, and glass have been used. In particular, touch panels are used as input devices to information terminals. It is possible to input desired information in the information terminal by touching a fingertip to the surface panel of the touch screen. [0003] When a fingertip touches the optical member, oil such as aliphatic hydrocarbons existing on the surface of the fingertip tends to form fingerprint marks and adhere thereto. Since the visibility of the optical member will be reduced when oil is attached to the optical member, when oil is attached, it is required at the same time: (1) It is easy to wipe off...
