Abstract
A dispersion of oil globules which contains an ultra-violet absorber and a high-boiling solvent is disclosed. The UV absorber is a mixture of 15 to 45 wt % of a compound of formula (I) and 85 to 55 wt % of a compound of formula (II): ##STR1## (wherein R.sub.1 and R.sub.2 each represents an alkyl group having 1 to 4 carbon atoms; X is a hydrogen atom, a halogen atom, a methyl group, an ethyl group, a methoxy group, an ethoxy group or an aryl group); ##STR2## (wherein R.sub.3 and R.sub.4 each represents an alkyl group, provided that the total number of carbon atoms in the alkyl groups represented by R.sub.3 and R.sub.4 is 9 or more; Y is a hydrogen atom, a halogen atom, a methyl group, an ethyl group, a methoxy group, an ethoxy group or an aryl group).
