Abstract
Radiation-setting compositions suitable for the formation of LCD spacers or protective layers which are excellent in photosetting properties (requiring no heat-setting) and development properties, have high adhesiveness to substrates and excellent mechanical characteristics, remain stable over a long storage time and show excellent working condition-dependency. Such a radiation-setting composition for the formation of LCD spacers or protective layers comprises a (meth)acrylic acid-based copolymer having an acid value of 30 to 200 and a glass transition temperature of -30 to 180.degree. C., a (meth)acrylate-based compound obtained by copolymerizing a monomer having a specific structure with a monomer at least having an acidic group, a radiation-sensitive compound and a solvent.
