Provided are methods for surface-modifying a thermoplastic resin which produce surfaces that show not only low adsorption of proteins and cells but also selective adsorption or adhesion of specific cells such as cancer cells, and further have excellent durability. A method for surface-modifying an object made of a thermoplastic resin, the method including: step 1 of forming polymerization initiation points on the surface of the object; and step 2 of radically polymerizing at least a hydrophilic monomer starting from the polymerization initiation points by irradiation with UV light having a wavelength of 300 to 400 nm to form a graft layer having a thickness of 2 to 100 nm on the surface of the object.

The present invention provides a coating method including: a step of supplying a coating agent to a surface of a lens base material; a spreading step of spreading the coating agent supplied to the surface by rotation of the lens base material; a first removal step of removing at least a part of a liquid pool of the coating agent generated on a peripheral edge portion and/or a side surface portion of the lens base material by rotation of the lens base material after the spreading step; and a second removal step of removing the liquid pool remaining on the peripheral edge portion and/or the side surface portion of the lens base material by bringing an adsorption member into contact with at least the side surface of the lens base material after the first removal step. According to the present invention, it is possible to provide a coating method capable of obtaining a base material having a coating layer excellent in uniformity of film thickness by reducing the liquid pool of the coating agent generated on the peripheral edge portion and/or the side surface portion of the lens base material when the coating layer is formed on the surface of the base material by spin coating the coating agent.

The present invention relates to a method for producing a multicoat paint system by producing a basecoat or a plurality of directly successive basecoats directly on a substrate coated with a first coat, producing a clearcoat directly on the one or the topmost of the plurality of basecoats, and subsequently jointly curing the one or the plurality of basecoats and the clearcoat. At least one of the basecoat materials is admixed, directly before application, either with an aqueous dispersion (D1) comprising a polyamide (PA) having an acid number of 15 to 60 mg KOH/g or with an aqueous dispersion (D2) comprising a polyamide (PA) and an amide wax (AW).

The object of the present disclosure is to provide an automobile part capable of improving fuel consumption by weight reduction of the part because the impact resistance that can be sufficiently used even in cold regions can be given to a part made of a thinner plastic.

An automobile part obtained by forming a coating film layer on a plastic material comprising a polypropylene resin composition modified with an elastomer component having a thickness of 1.5 to 2.5 mm, wherein said coating film layer is a multilayer coating film obtained by coating and baking the following coating compositions in this order; (a) a primer coating composition having a single film tensile elongation of 5 to 35% at −20° C., (b) a base coating composition containing a coloring agent and, (c) a clear coating composition containing at least a linear acrylic polyol (c-1) with a hydroxyl value of 80 to 220 mgKOH/g, a crosslinked acrylic resin (c-2) containing 2 to 30 parts by weight of polyfunctional monomer (c-2-1) with 2 to 4 radically polymerizable unsaturated groups per a molecule and 98 to 70 parts by weight of monofunctional monomer (c-2-2) with one polymerizable unsaturated group as a constituent unit, and having a glass transition point of 70 to 120° C., and a curing agent (c-3), and wherein the coating film layer has a Dupont impact strength of 4.9 J or more at −30° C.

Tunable thermoplastic polymer sealants and tunable conductive thermoplastic polymer sealants, and edge seals and fillet seals produced from such sealants; and substrates, components and objects comprising the tunable edge seals and fillet seals, and methods for making and applying such edge seals and fillet seals are disclosed.

In various embodiments, the present invention is directed to contact lenses that utilize a multilayer coating of alternating high RI materials, such as melanin or polydopamine (PDA) and other low RI materials to create tunable iridescent colors and contain melanin or similar materials that impart photoprotection due to their broadband UV-vis absorption spectrum and ability to quench radicals.

The invention relates to a pro-biofilm coating applied by means of cold atmospheric plasma polymerization of a precursor on a substrate. The coating has a roughness such that it promotes the creation of more than 100% biofilm on the substrate, where the 100% of biofilm is the one as produced on the same substrate being devoid of said pro-biofilm coating. The invention also relates to a method of producing said pro-biofilm coating and a substrate coated with same.

An object of the present invention is to provide a film forming method capable of improving a film forming speed in the film formation by an aerosol deposition.
