Abstract: A retroreflective composition of the present invention comprises non-volatile matrix material, volatile constituent, and a plurality of retroreflective microsphere beads wherein the ratio of the volume of matrix material to the volume of retroreflective microsphere beads is in the range of 75% to 185%, and is optimally suitable for use on fabrics.

Abstract: The present invention is an impact print bar assembly (10) adapted for installation in a typewriter, character printer or other device adapted for linear application of printed characters to sheet material. The assembly (10) includes an impact print bar (12) which is adapted to be held within a bar holder (14) in any of four different orientations, each of the orientations presenting a different print surface. The impact print bar (12) provides a solid, non-rotating, surface for the sheet material to reast against during printing. The impact print bar (12) includes a central support rod (28) having a resilient, usually plastic, body (36) formed thereabout. The degree of hardness of the body (36) may be varied, depending on the application desired. The support rod (38) has a square cross-section such that it will fit into the hollow frame (52) of the bar holder (15) in any of the four orientations.
