    摘要： A process for preparing an aqueous resin dispersion includes the steps of copolymerizing a polymeric monomer whose ratio of (meth) acrolein to a total amount of the (meth) acrolein and a vinyl monomer is in the range from 10 weight % to 80 weight % in an organic solvent to obtain a copolymer solution, dispersing the obtained copolymer solution in an aqueous medium and removing an unreacted (meth) acrolein. Since the above process can extremely reduce contents of the unreacted (meth) acrolein and of an oligomer whose number-average molecular weight is less than 1000, an aqueous resin dispersion where problems of a pungent smell, toxicological properties, etc. due to the (meth) acrolein and the oligomer are eliminated can be provided.

    摘要： A thermosensitive recording material comprising a recording layer formed on a substrate and a coating film layer formed thereon, wherein the recording layer is of a bilayer structure composed of a first thermosensitive layer on the side of the lower layer and a second thermosensitive layer on the side of the upper layer and particles are dispersed in at least one of the first and second thermosensitive layers. An original plate for lithographic printing can be produced from a combination of an ink-philic resin and an ink-repelling resin as the compositional materials of such thermosensitive layers. Besides, thermosensitive, recording materials for magnetic recording, thermosensitive materials for electrostatic recording, thermosensitive recording materials for colored image recording and the like, can be generated through a variety of modifications of the compositional materials. Then, the use of such thermosensitive recording materials attains thermosensitive recording at a higher precision through simple processes and procedures.
