Abstract (en)
IR-sensitive element comprising (a) a substrate with a hydrophilic surface, and (b) a positive working coating comprising (i) at least 40 wt.-%, based on the dry weight of the coating, of at least one polymer which comprises phenolic OH groups and/or sulfonamide groups and is soluble in aqueous alkaline developer, (ii) at least one arylpolysiloxane resin having a hydroxy content of at least 1 wt.-% based on the weight of the resin and a glass transition temperature in excess of 60°C, (iii) at least one substance capable of absorbing radiation of a wavelength from the range of 650 to 1,300 nm and converting it into heat, and (iv) optionally at least one further component selected from print-out dyes, plasticizers, surfactants, inorganic fillers, antioxidants, contrast dyes and pigments, and polymer particles.
