    Abstract: A process for the recycling of cured amino resins in which cured amino resins, optionally containing fillers, are treated with an aqueous sulphite, hydrogen sulphite or disulphite solution and the resultant low-molecular-weight degradation products are employed in chemical processes. The invention also relates to the low-molecular-weight degradation products of cured amino resins which are obtainable by this process, and to their use for the coating of mouldings, for the tanning of leather and hides, and for the production of mouldings containing or comprising cured amino resins.

    Abstract: A tetrachloroperylene-3,4,9,10-tetracarboxylic acid diimide pigment which contains not less than 85% by weight of the tetrachloro compound of the formula which is present to the extent of not less than 95% by weight in the beta -modification and which, in an X-ray spectrum, exhibits 2(-) CuK alpha main lines at 9.0 DEG , 13.3 DEG , 15.0 DEG , 16.8 DEG , 19.1 DEG , 21.5 DEG , 24.2 DEG , 25.4 DEG , 26.5 DEG , 27.0 DEG and 27.5 DEG . In finishes, the pigment gives very brilliant colorations which are very highly lightfast and fast to weathering and which, upon weathering, neither bleach nor darken up.
