A titanium alloy contains vanadium, from 10 to 20% by weight; aluminum, from 0. Specifically, the composition is comprised of a biopolymer that is preferably swellable andor mucoadhesive, a antimicrobial agent, and a cationic binding agent contained within the biopolymer such that the binding agent is tonically bound or complexed to at least one member selected from the group consisting of the biopolymer and the antimicrobial agent. 5% by weight with respect to the metal oxide particles and a contact angle of the metal oxide particles with respect to water is from 7\xb0 to 12\xb0; and a photosensitive layer which is provided on the undercoat layer. The holding members may be etched on a BGA socket top and are flexible, rigid andor semi-rigid to provide support for the solder balls. The circumference of the transport roller is equal to or less than at least one of the array height of the nozzle array or an image height of the reference image. The profile height decreases continuously from the high profile height to the low profile height, and the single hat profile extends into a double hat profile.
