Problems solved by technology
Due to the presence of fluorine-containing compounds on the surface after coating, it is affected by the fluorine function, and the self-sag occurs, and the uniformity cannot be maintained, resulting in pinholes
[0006] If the fluorine function is enhanced by increasing the ratio of perfluoroalkyl-containing monomers, the solubility in the composition becomes poor
Also, the sag issue occurs as described above
[0007] In addition, the method of concentrating on the structure of the monomer containing a perfluoroalkyl group is complicated and has problems in terms of cost.
[0008] In addition, when performing block polymerization, first of all, in this method, the search for a synthetic route containing heavy metals is itself a problem. When using other routes, due to the nature of the block polymerization method, perfluoroalkyl groups in the copolymer Aggregation, so there is still a tendency to cause depressions, and there is a problem of poor solubility in the composition
[0009] In addition, the block copolymer described in Patent Document 3 using another route does not use heavy metals and has good surface tension reduction performance, but this document does not describe the solubility of the copolymer due to the aggregation of perfluoroalkyl groups. Countermeasures against deterioration are not specifically described in the curable resin composition, nor are they specifically described in the solubility of the curable resin composition

Abstract
Subject of the present invention is to provide the curable resin combination, not using heavy metals and the long chain fluorinated alkyl, but using commonly known fluorine-containing monomer. The composition is used in the system excellent solubility, and suppresses the sag of fluoride compounds. Solution is a curable resin combination, and contains the following block copolymer resin, solvent (B) (A) and (C) block copolymer (A) : is 1% in quality concentration with propylene glycol monomethyl ether acetate, can be transparent liquid without gonorrhea block copolymer.
Description
technical field [0001] The present invention relates to a curable resin composition containing a block copolymer and its use. Background technique [0002] Photocurable resin compositions polymerized by ultraviolet light, visible light, etc. are used in various applications such as paints, adhesives, and coating agents. Among them, the resist composition is used as a photoresist composition and a color resist composition for a color filter of a liquid crystal display device, and it is desired to be able to form a particularly uniform coating film at the time of coating. [0003] In order to improve the uniformity of the coating film, the composition is required to have excellent leveling properties. [0004] In order to impart leveling properties, a fluorine-containing compound containing a perfluoroalkyl group is added to the composition. At this time, in order to better improve the leveling property, the following technology has been developed, which is to increase the r...
