- 3. The organic acid salt of melamine according to claim 2, wherein said carboxyl group-containing compound is selected from the group consisting of formic acid, acetic acid, propionic acid, butyric acid, lactic acid, glycolic acid, acrylic acid, methacrylic acid, oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, sebacic acid, maleic acid, itaconic acid, phthalic acid, hexahydrophthalic acid, 3-methylhexahydrophthalic acid, 4-methylhexahydrophthalic acid, 3-ethylhexahydrophthalic acid, 4-ethylhexahydrophthalic acid, tetrahydrophthalic acid, 3-methyltetrahydrophthalic acid, 4-methyltetrahydrophthalic acid, 3-ethyltetrahydrophthalic acid, 4-ethyltetrahydrophthalic acid, crotonic acid, trimellitic acid, and polybasic acid anhydrides of said polycarboxylic acids.
- 4. The organic acid salt of melamine according to claim 2, which is a salt obtained by the equimolar reaction of melamine with a dicarboxylic acid.
- 5. An organic acid salt of melamine obtained by the reaction of melamine with an acid phosphoric ester and represented by the following general formula (3) ##STR12## wherein R.sup.2 represents a hydrogen atom or an alkyl group or alkylene group severally having from 1 to 9 carbon atoms, or any of said groups whose hydrogen atom is substituted by acryloyl group or methacryloyl group, and R.sup.3 represents an alkyl group or alkylene group severally having from 1 to 9 carbon atoms, or any of said groups whose hydrogen atom is substituted by acryloyl group or methacryloyl group.

The organic acid salt of melamine according to claim 5, wherein said acid phosphoric ester is selected from the group consisting of monomethyl phosphate, dimethyl phosphate, monoethyl phosphate, diethyl phosphate, monopropyl phosphate, dipropyl phosphate, monobutyl phosphate, dibutyl phosphate, mono(2-acryloyloxyethyl) acid phosphate, di(2-acryloyloxyethyl) acid phosphate, mono(2-methacryloyloxyethyl) acid phosphate, and di(2-methacryloyloxyethyl) acid phosphate.
- 7. An organic acid salt of melamine obtained by the reaction of melamine with a sulfonic group-containing compound and represented by the following general formula (4) ##STR13## wherein R.sup.4 represents an alkyl group or aromatic hydrocarbon severally having from 1 to 18 carbon atoms, or any of said group or hydrocarbon whose hydrogen atom is substituted by acryloyl group or methacryloyl group.
- 8. The organic acid salt of melamine according to claim 7, wherein said sulfonic group-containing compound is selected from the group consisting of methanesulfonic acid, p-toluenesulfonic acid, dodecylbenzenesulfonic acid, naphthalenesulfonic acid, and sulfoethylmethacrylate.
