Abstract
An aqueous deformation-detecting brightener composition that can easily detect deformation such as unevenness on the surface of a car body by forming a liquid thin film having low foaming property and excellent glossiness is provided by dissolving a glycol ether compound expressed by the following formula (I) and a surfactant in water EQU R.sup.1 --O--(AO).sub.m --R.sup.2 (I) where "R.sup.1 " represents an alkyl group having 1 to 9 carbon atoms, an alkenyl group having 1 to 9 carbon atoms, an alkylphenyl group having 1 to 9 carbon atoms, or a functional group expressed by the following general formula (II), "A" represents an alkylene group having 2 to 4 carbon atoms, "m" represents an average adduct molar number of alkylene oxide, a number of 1 to 20, in which the same alkylene oxide may be added alone, or a mixture of two or more types of alkylene oxide may be added, and "R.sup.2 " represents an alkyl group having 1 to 9 carbon atoms, an alkenyl group having 1 to 9 carbon atoms, or hydrogen EQU Ph--(CH.sub.2).sub.n -- (II) where "Ph" represents a phenyl group, and "n" represents an integer of 0 to 3.
