A blend of optical brighteners includes (a) from 45 to 95 weight % of a mixture of benzoxazolyl stilbenes; and (b) from 55 to 5 weight % of at least one bis(benzoxazolyl)naphthalene based brightener, bis(benzoxazolyl)thiophene based brightener, a pyrazoline based brightener, a coumarin based brightener, and mixtures thereof, wherein the weight percents of the optical brightener blend are based on the total weight of optical brighteners in the blend. The optical brightener blend is useful for admixing with a polyolefin resin which in turn may be used for photo imaging applications.
