Microcapsules having a capsule core comprising water-soluble organic substances, and a capsule coating which is a condensate of formaldehyde resins and/or alkyl ethers thereof, a process for their preparation, their use, and compositions comprising the microcapsules.

Micro-capsules comprising a capsule core containing water-soluble substances

The present invention relates to the use of at least one radiation crosslinkable, preferably UV crosslinkable, polymer composition as a data recording medium, especially in the form of what are known as smart coatings based on such polymer compositions, which in a further embodiment comprises at least one fluorescence chromophore, and also to a composite at least comprising one support and one layer comprising a radiation crosslinkable polymer composition comprising at least one fluorescence chromophore, and also, preferably, an additional UV absorbing layer.

Utilization of beam crosslinkable polymer compositions as data recording medium

Adhesive-coated, peelable protective films and peelable labels, wherein the adhesive contains a copolymer that is capable of undergoing free-radical polymerization and which comprises, to an extent of from 0.1 to 10 wt %, based on the copolymer, a compound A compound of at least one copolymerizable, ethylenically unsaturated group and a group of the formulain which Rand Rindependently stand for hydrogen or a C-Calkyl group or Rand Rtogether form a bridging C-Calkylene group which can be mono- or di-substituted by a C-Calkoxy group or hydroxyl group and X stands for O or S.
