The invention provides a coating composition comprising a coating solution of a polymeric binder and an organic solvent having a gammac hydrogen bonding parameter value greater than 9.0, the coating solution having dispersed therein a titanyl fluorophthalocyanine pigment which has been acid-pasted or salt-milled to increase its photosensitivity and then has been brought into contact with an organic solvent having a gammac hydrogen bonding parameter value less than 8.0 to preserve its increased photosensitivity, prior to the pigment's being dispersed in the coating solution.
