The present invention concerns functionalized photoreactive compounds of formula (I), that are particularly useful in materials for the alignment of liquid crystals. Due to the adjunction of an electron withdrawing group to specific molecular systems bearing an unsaturation directly attached to two unsaturated ring systems, exceptionally high photosensitivities, excellent alignment properties as well as good mechanical robustness could be achieved in materials comprising said functionalized photoreactive compounds of the invention.
The present invention relates to novel compounds that are particularly useful for the alignment, especially photoalignment, of slave material, especially liquid crystals for optical or electro-optical applications, such as security applications, liquid crystal devices or optical or electro-optical films.

Disclosed matters which can be degraded and disappear in the natural environment are a degradable adhesive film which can be used for surface protection or indication after printing on the film surface and has an adhesive layer on one side of a substrate film obtained from a lactic acid base polymer such as polylactic acid and a lactic acid/hydroxycarboxylic acid copolymer having a molecular weight of 30,000∼500,000, and a degradable resin composition which is excellent in weatherability and comprises 100 parts by weight of a lactic acid base polymer and 0.001∼5 parts by weight of one or more additives selected from ultraviolet absorbers and light stabilizers.
This invention provides a degradable resin composition which has inhibited decomposition and excellent weatherability primarily in outdoor use.
This degradable resin composition comprises 100 parts by weight of a lactic acid base polymer and 0.001 to 5 parts by weight of one or more additives selected from an ultraviolet absorber and a light stabilizer.
A membrane formed by coating an aqueous coating liquid comprising an antistatic agent or anticlouding agent on one or both surfaces of an aliphatic polyester film comprising a specific amount of a lubricant or an antiblocking agent, can remarkably improve adhesion of the membrane (antistatic layer or anticlouding layer) to the aliphatic polyester film, and thus the effect of the membrane (antistatic effect or anticlouding effect) can be continuously exhibited for a long period.
