Abstract: PROBLEM TO BE SOLVED: To obtain a fluorescent brightener mixture which can synergistically improve the whitening effect of a synthetic resin by combining two brighteners selected from specified compounds. SOLUTION: This mixture is a fluorescent brighter comprising below described and B, represented by formulas I and II (wherein R and R are each hydrogen, a 1-10 C alkyl or the like; and X is a 1,4-naphthylene group, a 2,5- thiophene group or a 2,5-furan group) and at least one brighter represented by formula III (R in position 5 is hydrogen, a halogen, a 1-4 C alkyl or a phenyl, R is hydrogen or R and R in positions 5 and 6 or positions 5 and 7 are each methyl; n is 0 or 1; and B is cyano, carbo-1-4 C-alkoxyl or the like). This mixture is desirably prepared by mixing components A and B with each other in an A/B weight ratio of (20-80%)/(80-20%). This mixture is used in an amount of 1-5,000ppm based on the resin.
