Embodiment 1

[0094] [Example 1] Production of Alkaline Developable Resin Composition No.1

[0095] Production of 1,1-bis(4'-hydroxyphenyl)-1-(1"-biphenyl)-1-cyclohexylmethane

[0096] 70.5 g of biphenylcyclohexyl ketone, 200.7 g of phenol, and 10.15 g of thioacetic acid were added, and 40.0 g of trifluoromethanesulfonic acid was added dropwise at 18° C. over 20 minutes. After reacting at 17-19° C. for 18 hours, 500 g of water was added to stop the reaction, 500 g of toluene was added, the organic layer was washed with water until its pH reached 3-4, and the organic layer was separated. Toluene, water and excess phenol were distilled off. Toluene was added to the residue, and the precipitated solid was filtered, dispersed and washed with toluene to obtain 59.2 g of pale yellow crystals (51% yield). The melting point of the pale yellow crystals was 239.5° C., and it was confirmed that the pale yellow crystals were the target compound.

Abstract

An alkali and negative resin combination, which contains the outcome from making oxygen-linked addition compound many entity anhydrides (C) the multi-functional oxygen-linked compound esterified. The oxygen-linked addition compound, possessing a oxygen-linked radical owned by oxygen-linked resin (A), has the structure shaped by combining oxygen-linked resin expressing with unsaturated unified acid (B) whose structure is shaped by combining at the rate on carboxyl group of 0.1-1.0 and the formula (I) in which the definition of each parameter is seen in the introduction. The esterification is carrying out at the rate of one hydroxyl group in the oxygen -linked addition compound, 0.1-1.0 anhydride structure in the many entity anhydrides (C) and 0.1-1.0 oxygen-linked radical in the multi-functional oxygen-linked compound (D).

Description

technical field [0001] The present invention relates to an alkali-developable resin composition containing a specific compound having an ethylenically unsaturated bond, an alkali-developable photosensitive resin composition containing a photopolymerization initiator in the alkali-developable resin composition, And the manufacturing method of this alkali-developable resin composition. Background technique [0002] The alkali-developable photosensitive resin composition contains the alkali-developable resin composition and photoinitiator which contain the compound which has an ethylenic unsaturated bond. The alkali-developable photosensitive resin composition can be polymerized and cured by irradiating ultraviolet rays or electron rays, so it is used in photocurable inks, photosensitive printing plates, printed circuit wiring boards, and various photoresists. agent etc. Recently, along with the development of thinner, thinner, and higher performance electronic devices, an al...
