| 摘要 |
This invention describes an improved ionizing radiation sensitive material having high contrast, high sensitivity and comprised of a metal complex of a mixed half-ester or half amide product of the reaction of an N-hydroxy or N-aminoalkyl amide and a hydroxy alkyl terminally unsaturated compound with an alkylvinyl ether-maleic anhydride copolymer. A typical material is made by reacting a metal salt with the mixed half-ester or half-amide product of the reaction of an N-hydroxy or N-amino alkyl amide and a hydroxy alkyl terminally unsaturated compound with an alkyl vinyl ether-maleic anhydride copolymer.
