Abstract
A method for forming an image includes the step of desensitizing a radiation sensitive imaging system comprising a dye and a tetra (hydrocarbyl) borate in a binder by converting the tetra (hydrocarbyl) borate to a compound having fewer than four carbon-to-boron bonds.
Claims26
A method for desensitizing a radiation sensitive imaging system comprising a dye and a tetra(hydrocarbyl)borate in a binder which method comprises converting the tetra(hydrocarbyl)borate to a compound having fewer than four carbon-to-boron bonds after said radiation sensitive imaging system has been imagewise exposed to radiation, said converting being effected by introducing into reactive association with said borate a material selected from the group consisting of acids, aldehydes, peroxides, quinones, iodine or readily reducible metal ions.
