A hot-melt adhesive comprising a thermoplastic resin and a first crystalline material, wherein when in differential scanning calorimetric measurement of the hot-melt adhesive, Tc (° C.) is a peak temperature of the highest peak of exothermic peaks observed in a temperature reduction process at 10° C./min following heating to 150° C. and Tm (° C.) is a peak temperature of the highest peak of endothermic peaks observed in a temperature increasing process at 10° C./min following the temperature reduction process, Tm-Tc is 20.0 to 70.0° C., and a tetrahydrofuran-soluble matter of the hot-melt adhesive has a weight-average molecular weight Mw, as measured by gel permeation chromatography, of 100,000 to 400,000.

A fluidic ejection cartridge and protective tape therefor. The cartridge includes a cartridge body for an organic solvent-based fluid having a cover closing a first end thereof, an ejection head on a second end thereof and side walls attached to the first and second ends between the first and second ends. The side walls include a first side wall, a second side wall opposite the first side wall, a first end wall attached to the first and second side walls, and a second end wall opposite the first end wall attached to the first and second side walls. A removable tape is attached to a nozzle plate of the ejection head and to a portion of the first side wall. The removable tape contains a polymeric backing film and a glass-filled, platinum-cured silicone adhesive.

examining each of the prepared TLCP films for a relative intensity calculated as a ratio in percentage of a sum of peak areas of C—O bond peak and COO bond peak based on the total area of C1s peaks in the XPS spectral profile so as to calculate a relative intensity X (%) as for the prepared adherend film and a relative intensity Y (%) as for the prepared adhesive film; and

controlling the TLCP film as the adhesive film to have a relative intensity Y by selection or activation treatment of the adhesive film so that the relative intensity X of the adherend film and the relative intensity Y of the controlled adhesive film satisfy the following formulae (1) and (2):

38<X+Y<65   (1)

−8.0<Y−X<8.0   (2).
