Class Information
Number: 430/237
Name: Radiation imagery chemistry: process, composition, or product thereof > Transfer procedure between image and image layer, image receiving layers, or element containing an image receiving layer or an ingredient for forming an image receiving layer > Diffusion transfer process, element, or identified image receiving layers therefor > Dye image formation process > Using silver salt sensitizer > Using identified neutralization layer or ingredient or separate post transfer treatment of dye image
Description: Processes employing an identified neutralization layer or ingredient which adjusts the pH of a processing composition used in forming the dye image to a substantially more neutral pH or treating a formed dye image.
