Abstract: A method of directly forming a light scattering image, wherein a recording layer is information-wise exposed in the visible light spectral region to a light energy dose of at least 10.sup.-1 Ws cm.sup.-2 with a focussed laser-beam having a beam intensity of at least 10.sup.4 W cm.sup.-2. The recording layer is a thermoplastic polymer layer having dissolved therein at least one substance absorbing visible light, which substance imparts a specular density to the recording layer of at least 0.1 with respect to a monochromatic wave of the laser-beam applied in the exposure and is present in an amount of maximum 10% by weight with respect to the thermoplastic polymer of the layer, the recording layer being capable of directly developing in the areas struck by said beam, minute light-scattering centers providing a minimum increase of white light specular density of 0.2 when measured with respect to a transparent background and determined as described hereinbefore, but being incapable of developing such centers when exposed with the same laser-beam at an intensity reduced by a factor of 10.
