Homopolymers suitable for storage of information provided optically are disclosed. The are formed from monomers which contain groupings which are at least trinuclear, which are capable of absorbing the electromagnetic radiation of visible light, and which are structured so that in their thermodynamically stable state they are distended and strongly anisometric, wherein the at least trinuclear groupings comprise at least one electron-attracting substituent which gives rise to a dipole moment which forms an angle of at least 20° with the longitudinal axis of the at least trinuclear groupings,
wherein the at least trinuclear groupings contain at least one nucleus-linking group which is suitable for a photo-induced change in configuration, wherein said group is selected from the set consisting of

Dental materials which contain a radically polymerizable organic binder, at least one radical polymerization initiator and at least one radical polymerization accelerator, both the initiator and the accelerator each having at least one radically polymerizable group.
An antifouling agent comprising as an antifouling component a substantially linear triorganotin-containing copolymer containing (a) at least one kind of N-coordinated triorganotin-containing recurring units of the formula (la) or (Ib) represented in the specification and (b) comonomer recurring units derived from at least one ethylenic vinyl compound as a comonomer.
The antifouling agent is applied to a structure which is needed to be protected from fouling organisms to form a film of the copolymer on the structure.
