    Abstract: A resist film comprises a dimensionally stable base (B), which is transparent to actinic light in the wavelength range from 300 to 420 nm, and a mask-forming layer (ML) which is sensitive to heat radiation and contains a thermochromic system which, when irradiated with an IR laser having a wavelength greater than 1.00 .mu.m, undergoes an irreversible change in its absorption spectrum in the wavelength range from 300 to 420 nm so that the optical density of the mask-forming layer (ML) in this wavelength range changes by not less than 1.3 units. The base of the resist film can also be applied onto the photosensitive relief-forming layer (RL) of a recording material to give a multilayer image-recording material. Imagewise irradiation with heat, for example using an IR laser, produces, in the mask-forming layer (ML) of the resist film, a UV photomask which is very useful for exposing photosensitive recording materials.

    Abstract: A heat-sensitive recording material comprises a heat-sensitive layer which is applied onto a base and contains a color-producing substance, which is usually colorless or only slightly colored, and an activator which, under the action of heat, causes the color-producing substance to produce a coloration. In accordance with the invention, the heat-sensitive layer contains a sulfonic acid ester, in particular of a secondary alcohol, as the activator.
