    Abstract: Naphtholactamsquaric acid dyes of the formula ##STR1## where R.sup.1 and R.sup.2 independently of one another are each unsubstituted or substituted C.sub.3 -C.sub.22 -alkyl, in which the alkyl chain may be interrupted by oxygen atoms, or are each unsubstituted or substituted C.sub.1 -C.sub.4 -aralkyl, unsubstituted or substituted C.sub.5 -C.sub.7 -cycloalkyl or unsubsituted or substituted phenyl, and the rings A, B, C and D are unsubstituted or substituted and/or benzofused, and optical recording materials consisting of a base and a layer which is sensitive to laser light and is composed of a thermoplastic or crosslinked polymer and one or more dyes (I).Because of the high light absorption of (I), the recording materials are very sensitive to light from the GaAlAs semiconductor laser. An excellent signal-to-noise ratio is obtained on reading the recordings.

    Abstract translation: 其中R 1和R 2彼此独立的式（I）的萘酚酸盐酸染料均为未取代或取代的C 3 -C 22 - 烷基，其中烷基链可被氧原子间隔，或者各自为未取代或取代的C1 -C 1-4 - 芳烷基，未取代或取代的C 5 -C 7 - 环烷基或未取代或取代的苯基，并且环A，B，C和D是未取代或取代和/或苯并稠合的光学记录材料， 对激光敏感，由热塑性或交联聚合物和一种或多种染料（I）组成。 由于（I）的高吸收光，记录材料对GaAlAs半导体激光器的光非常敏感。 在读取记录时获得良好的信噪比。

    Abstract: Laminates for the manufacture of flexographic printing plates and containing (a) a layer consisting essentially of a photocrosslinkable mixture of a two-block copolymer of from 30 to 95% w/w of a diene hydrocarbon and from 5 to 70% w/w of a styrene monomer or a partially hydrogenated product thereof with a compatible monomer having at least one C--C double bond, said mixture containing a photo-initiator, (b) a non-photocrosslinkable elastomeric underlayer having a Shore A hardness of from 15 to 70 and (c) a non-photocrosslinkable stablizing layer preferably between layers (a) and (b).
