Abstract:
To provide an inkjet ink polymer capable of providing an inkjet ink capable of forming a printed product having excellent weather resistance, print density (coloring properties), and fixability (abrasion properties) with good productivity and providing a pigment dispersion having excellent dispersibility with good productivity. An inkjet ink copolymer contains 10 to 99% by weight of a cyclohexyl methacrylate unit and 1 to 90% by weight of an acrylic acid unit. The purpose is achieved by an inkjet ink pigment dispersion containing the inkjet ink copolymer and a pigment.
Abstract:
An anode substrate constituted of a conductive film forming substrate and a reinforcing substrate having different thermal expansion coefficient and being bonded together by the arrangement of adhesive layers is disclosed. The substrate can prevent creation of cracks on the conductive film forming substrate when heating and cooling the anode substrate. The adhesive layers are arranged at an interval, each of the adhesive layers being formed into a shape selected from a group consisting of a rectangular strip shape and a curved strip shape. The adhesive layers are arranged in a pattern to be symmetry with respect to a center line of the arrangement of the adhesive layers extending perpendicular to a line connecting both longitudinal ends of the arrangement of the adhesive layer. Furthermore, the adhesive layers include an outer adhesive portion located outward among remaining adhesive layers, and the outer adhesive layers are arranged shorter than the remaining adhesive layers.
Abstract:
In some embodiments, a drum unit may include an electrophotographic photosensitive member having a base member and a photosensitive layer on the base member. An embodiment may include a cleaning blade configured to abut the photosensitive layer to remove a developer remaining on the photosensitive layer of the electrophotographic photosensitive member. Some embodiments may include side seals disposed at both ends of the cleaning blade to inhibit leakage of the developer. In some embodiments, a portion of a side seal may be in contact with at least a portion of the surface and an end face of the photosensitive layer.
Abstract:
A touch switch includes a glass substrate; a lattice pattern formed on the glass substrate by a plurality of first line wirings and a plurality of second line wirings; and a non-transparent insulating member formed on the first line wirings and the second line wirings. The plurality of first line wirings are arranged at a predetermined interval. The plurality of second line wirings are arranged at a predetermined interval to intersect the first line wirings. The sensor units and dummy sensor units are formed to be electrically isolated from each other and adjacent to each other by separators provided in the first and second line wirings of the lattice pattern. Marks are formed by the non-transparent insulating member and a transparent opening section, the marks being arranged in positions corresponding to the sensor units.
