Abstract: A film-forming resin which is a copolymer of (meth)acrylamide and (meth)acrylate monomers is disclosed. The film-forming resin can sustain a hair style over a prolonged period of time, even under high humidity, when used in a hair care product. Further, it is excellent in shampoo-washability and set-retaining power.

Abstract: A film-forming resin which is a copolymer comprising specific monomers and a hair dressing composition containing the film-forming resin are disclosed. This film-forming resin is highly compatible in LPG and thus useful in the replacement of conventionally employed Freon gas by LPG. The hair dressing composition shows excellent effects including a good set-retention.

Abstract: A structure is provided for securing a casing of a car stereo on a periphery of an opening formed in a dashboard of a motor vehicle. A screw is rotatably supported in the casing by supporting members, and a movable member is engaged with the screw to be moved along the screw by rotating the screw. A clamping member is pivotally and axially movably mounted on the screw. When the movable member is moved, and engages with the clamping member, the clamping member is pivoted and axially moved. The clamping member has an arm and a clamping portion provided to be abutted on an inside wall of the dashboard when the clamping member is pivoted and axially moved, whereby clamping the dashboard. The arm has an engaging projection which is engaged with a side wall of the casing so that the clamping member is prevented from deforming.
