Embodiment 1

[0104] [Example 1] Production of Photocurable Resin No.1

[0105] In a 1L four-necked flask with stirring device, nitrogen inlet pipe, reflux cooling pipe and thermometer, add 75.0g of bisphenol fluorene type epoxy resin (epoxy equivalent is 231) as a difunctional epoxy compound, 23.8g as Acrylic acid of unsaturated monobasic acid, 0.273g 2,6-di-tert-butyl-p-cresol, 0.585g tetrabutylammonium chloride and 65.9g propylene glycol-1-monomethyl ether-2-acetate at 90°C The mixture was stirred for 1 hour at 100° C., 1 hour at 110° C., 1 hour at 110° C. and 14 hours at 120° C. to obtain component (C). After cooling to room temperature, 55.6 g of commercially available polyethylene glycol monomethyl ether (Uniox M-1000 manufactured by NOF Corporation) with a number average molecular weight of 1000 as the component (B) and 2,4 - 28.6 g of toluene diisocyanate, 0.182 g of dibutyltin dilaurate, and 206 g of propylene glycol-1-monomethyl ether-2-acetate were stirred at 70° C. for 2 hours....

Embodiment 2

[0107] [Example 2] Production of Photocurable Resin No.2

[0108] 1, the synthesis of 1-bis(4-hydroxyphenyl)indan

[0109] In a 2L four-neck flask equipped with a stirring device, a nitrogen inlet pipe, a reflux cooling pipe, and a thermometer, add 200g of indanone and 855g of phenol under a nitrogen atmosphere, slowly add 59.4g of sulfuric acid dropwise at 40°C, and then dropwise add 16.1 g 3-mercaptopropionic acid. After the dropwise addition, it was stirred at 55° C. for 20 hours, 300 g of ethyl acetate and 50.4 g of 48% by weight aqueous sodium hydroxide solution were added for neutralization, and the precipitated crystals were filtered to obtain 224 g of a crude product. The crude product was dissolved in 1450 g of ethyl acetate, washed with 500 g of 5% by weight ammonium acetate aqueous solution until the pH of the organic layer reached 4 to 5, and 50 g of anhydrous magnesium sulfate was added to the organic layer after the liquid was separated, and dried . The solve...

Abstract

The invention provides a dispersing agent which has the advantages of high dispersibility as well as high light-solidification property and high adhesion on a base material during film coating. In the dispersing agent, a light-solidified resin is used, and the light-solidified resin is obtained by the method as follows: adding a diisocyanate compound (A) into a compound (B) which has one or two hydroxyl groups in the same molecular and has a number-average molecular weight of 300-5000 and a compound (C) which has two hydroxyl groups and two ehtylenic bond type unsaturated groups in the same molecular; and then carrying out Michael addition in a compound (D) which has active hydrogen and tert-amino in the same molecular.

Description

technical field [0001] The present invention relates to a novel photocurable resin having a specific structure and a dispersant using the resin. Background technique [0002] Conventionally, in the fields of paints and inks, various dispersants have been used to improve the dispersibility of pigments, the storage stability of paints, etc., and the gloss of coating films. For example, patent document 1 discloses a dispersant obtained from a compound having at least one nitrogen-containing basic group, and patent document 2 discloses the reaction of polyisocyanate, acrylate compound or epoxy compound with a cyclic compound. As a dispersant obtained from the obtained reaction product, Patent Document 3 discloses a resist composition for color filters using a specific dispersant resin as a dispersant. [0003] In recent years, in order to impart photocurability to the dispersant itself, attempts have been made to improve compatibility with photocurable adhesives, photocurabilit...
