The glycidyl methacrylate reaction of compound and obtain material, make containing carboxy resin (9) with as containing unsaturated group
The glycidyl methacrylate copolymerization of compound and the material that obtains, have the anxiety that chloride ion impurities quantitative change is many.It addition, synthesis
During polyurethane resin, it is also possible to use epoxy acrylate modified feedstock as diatomic alcohol compounds.Although introducing chloride ion
Impurity, but can use from the viewpoint of can controlling chloride ion impurities amount.
Above-mentioned this containing carboxy resin owing to having multiple free carboxy on the side chain of trunk polymer, the most permissible
Developed by alkaline aqueous solution.
It addition, the above-mentioned acid number containing carboxy resin is preferably the scope of 40~150mgKOH/g, more preferably 40~
The scope of 130mgKOH/g.When acid number containing carboxy resin is less than 40mgKOH/g, alkali development becomes difficulty, on the other hand, exceedes
During 150mgKOH/g, the dissolving of the exposure portion caused due to developer solution is accelerated, and line becomes thinner than required, exposure portion sometimes
With unexposed portion indistinction be dissolved by the developing stripping, it is difficult to describe normal corrosion-resisting pattern.
Additionally, the aforementioned weight average molecular weight containing carboxy resin is different according to resin matrix, it is usually preferred to 2000~
The scope of 150000, further preferably 5000~100000 scope.When weight average molecular weight is less than 2000, non-stick sometimes
Difference, the moisture-proof of the film after exposure is poor, and film thickness loss occurs during development, and image resolution ratio significantly deteriorates sometimes.The opposing party
Face, when weight average molecular weight is more than 150000, developability is significantly deteriorated, and storage-stable is poor.
Such compounding amount containing carboxy resin is 20~60 mass % in all compositions, preferably 30~50 matter
Amount %.When this compounding amount is less than above-mentioned scope, coating strength reduces, therefore the most preferred.On the other hand, this compounding amount is more than above-mentioned model
When enclosing, viscosity uprises or coating etc. reduces, therefore the most preferred.
