G03H2260/50 - CPC Classification

Classification description:

Recording materials or recording processes Reactivity or recording processes

Sub-classes:

G03H2260/51 » Photoanisotropic reactivity wherein polarized light induces material birefringence, e.g. azo-dye doped polymer 9
G03H2260/52 » Photochromic reactivity wherein light induces a reversible transformation between two states having different absorption spectra 22
G03H2260/53 » Photoconductor thermoplastic reactivity wherein light is transformed into an electrostatic then into a thickness distribution 9
G03H2260/54 » Photorefractive reactivity wherein light induces photo-generation, redistribution and trapping of charges then a modification of refractive index, e.g. photorefractive polymer 39
G03H2260/61 » Producing material deformation 3
G03H2260/62 » Direct etching 21
