Abstract: Particularly smudge-resistant ink jet images are produced with an ink jet recording material which comprises a support, at least one layer applied to the support and an agent which binds ink jet dyes in a spread- and smudge-resistant manner, wherein the agent exhibits a concentration gradient such that the further is the agent from the support, the lower is the concentration.

R1 means an optionally substituted thienyl, pyrroly, indolyl, furamyl or phenyl,
in which
R5, R6, R7, mean H or R5 and R6 together or R6 and R7 together mean the remaining members of a fused benzo ring and the residual substituent means H and
R2, R3, R4, R8, R9, R10 and M have the meaning stated in the description, is distinguished by elevated sensitivity and improved latent image stabilitity.

Abstract: A daylight reloadable lighttight plastic cassette for holding and dispensing a roll of light sensitive material is formed of a hollow open-ended tubular housing having lighttightly mating hingedly connected base and lid sections which pivot apart on the hinge to open the housing, A dispensing slot lighttightly sealed, e.g. by plush fabric, is present on the housing side opposite the hinge, preferably defined between suitably spaced longitudinal edges of the housing sections. The opposite housing ends are lighttightly closed by end caps, each molded in two mating sections, which are telescopingly fitted on end margins of the housing sections. The end cap sections can be carried by the respective housing sections to pivot therewith in clam-shell fashion. The housing sections can be latched in closed position, preferably with latches engaging the end cap sections.
