    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.

    Abstract: An optical recording medium comprises a transparent support; a laser-sensitive dye contg. layer; and a reflective layer contg. a silicon-phthalocyanine deriv. of formula (I) in whcih R1 is bounded to the phthalocyanine residue, R1 = H, 1-12 C alkyl, 1-12 C alkoxy, halogen or -Si(R2)(R3)(R4) in which R2, R3 and R4 each = 1-5 C alkyl; n = 1, 2, 3 or 4; and A and B each = 1-12 C alkyl, halogen or -OR5 in which R5 = 1-12 C alkyl which is opt. interrupted by one or more O atoms or 1-14 C alkylimino gps. and/or which is opt. substd. by a 5- or 6-membered satd. heterocyclic residue, or a gp. Si(R2)(R3)(R4) where R2, R3 and R4 are as above.

    Abstract: Information is stored in an optical recording medium containing a transparent base and a radiation-sensitive, dye-containing layer by means of a semiconductor write laser and read back by means of a semiconductor read laser, the wavelength of the write laser being less than that of the read laser. Examples of the medium and the wavelengths are given.
