Abstract (en)

Photographic elements which may be imaged by laser scanners emitting in the near infrared without the formation of interference fringes comprising a support bearing one or more layers of a silver halide emulsion having grains of a average diameter of no more than 0.4 micron, the element including one or more of: (i) a topcoat layer which is an outermost layer on the same side of the support as the photosensitive emulsion which topcoat layer is a diffuse transmitting layer with respect to near infrared radiation, (ii) a backing layer which is an outermost layer on the side of the support remote from the photosensitive emulsion which backing layer is a diffuse reflecting layer or absorbing layer with respect to near infrared radiation, (iii) a subbing layer which is positioned between the support and the photosensitive emulsion which subbing layer is a diffuse transmitting or absorbing layer with respect to near infrared radiation. Whereby the the element may be imaged by a laser scanning system emitting near infrared radiation substantially without formation of non-contact interference fringes.
