Problems solved by technology

In contrast, liquid crystal displays and surface protection films are required to have oil resistance, which is a characteristic that oil stains are not easy to adhere to, and there is a problem that sufficient oil resistance cannot be obtained with conventional thermosetting self-healing materials

Abstract

The invention provides a composition with which cured product having self-healing property is obtained and a self-healing coat film having cured coating layer thereof. The composition can be made into surface coat film with good self-healing property, good hardness as well as good UV-resistance. The self-healing coat film is provided with capsule which is obtained from solidification of the composition and shows full-light transmittance higher than 90%; solidified compositions such as solidified coat film with good self-healing property, hardness and oil-resistance and a self-healing coat film provided with the same are provided. A composition is characterized by comprising (A) polyhydric alcohols, (B) polyisocyanates and (C) at least one hindered amine light stabilizer, wherein the hydroxyl value of the (A) polyhydric alcohols is 150 to 400mgKOH / g, and the (C)hindered amine light stabilizer is a composition expressed by the general formula(1).

Description

technical field [0001] The present invention relates to a composition for forming a material having self-healing properties, for example, to a composition capable of forming a coating film used in liquid crystal displays of mobile devices such as mobile phones and personal computers, automobile bodies, etc. In the case of the surface protection film, it has both good self-healing and excellent film hardness, and also has UV resistance or oil resistance. Background technique [0002] Conventionally, plastic films subjected to hard coat treatment are used as surface protection films for optical components such as liquid crystal panels, automobile bodies, and the like. In general hard coating films, the hardness of the coating film is increased by increasing the crosslinking density, so the surface of the coating film can be hardened. Thereby, the scratch resistance of the surface of a coating film improves, and the surface of the screen of a liquid crystal display, the body o...
