摘要

Composition sensitive to radiation, the radiation sensitive element, a process to form an image on an element sensitive to radiation, the element is converted into the image.Process for producing an element sensitive to radiation, and use of a composition sensitive to radiation.The element sensitive to radiation, comprising: (a) one or more kinds of monomers each comprising at least an unsaturated group etilenicamente accessible by a free radical polymerisation.(b) at least one sensitizer.(c) at least one co initiator capable of forming free radicals with the sensitizer (b) and selected the following classes of compounds: metalocenos; derivatives of 1.3.5 - triazine with a three groups CX ~ 3 ~.In which X represents chlorine or bromine; peroxides; hexaarilbiimidazu00f3is; oxime ethers; oxime esters; N - arilglicinas and its derivatives; thiol compounds; acid N - aril.S - aril and - aril polycarboxylic with at least 2 carboxyl groups, at least one of which is connected to the atom n,S or the unit arila; alquiltriarilboratos; ethers benzou00ednicos benzou00ednicos; esters; tri - halogenometilarilsulfonas; amines; acid esters n,N - dialquilaminobenzu00f3ico; sulfonyl aromatic halides; tri - halogenometilsulfonas imides; diazossulfonatos; derivatives; 9.10 - diidroantraceno; 244 and - 244 - hydroxy amino acetophenones; and (d) optionally one or more components selected from alkali soluble binders, colorants, indicators of exposure.Plasticizers, transfer agents in the chain leucocorantes, surfactants.Inorganic fillers and inhibitors of termopolimerizau00e7u00e3o characterized in that at least a sensitizer is a derivative of the formula (1) oxazol, in which each ru00ac 1u00ac,Ru00ac 2u00ac and ru00ac 3u00ac is independently selected from a halogen atom, an optionally substituted alkyl group, a group arila optionally replaced, which can also be fused.A group aralquila optionally replaced, a group nru00ac 4u00ac ru00ac 5u00ac and a group oru00ac 6u00ac, in which ru00ac 4u00ac and ru00ac 5u00ac are independently selected from a hydrogen atom, an alkyl group,Arila or aralquila, ru00ac 6u00ac is an alkyl group, arila or aralquila or a hydrogen atom, and (k, m and N are independently o or an integer of 1 to 5.
