    摘要： The present invention relates to aqueous polymer dispersions having a polymer content of at least 55% by weight that are suitable for pressure sensitive adhesives. The invention also relates to a process for preparing these aqueous polymer dispersions and also to the use of the aqueous polymer dispersions in pressure sensitive adhesives and, respectively, pressure sensitive adhesive compositions, especially in pressure sensitive adhesives for transparent substrates, such as plastics labels. The aqueous polymer dispersions have a polymer content of at least 55% by weight, based on the total weight of the dispersion, the polymer being composed of ethylenically unsaturated monomers M and having a glass transition temperature below −10° C., in which the dispersed polymer particles have a polymodal particle size distribution, in which at least 70% by weight have a particle diameter of below 350 nm.

    摘要： A crosslinkable composition for coating primed and unprimed substrates comprising from 10 to 80 percent by weight of a hydroxy functional polydiene polymer having a functionality of at least 1.3, 8 to 60 percent by weight of an amino resin crosslinking agent, and 2 to 40 percent by weight of a reinforcing agent. The invention also encompasses a process to make such compositions by partially reacting the three components for 0.5 to 10 hours at 60.degree. to 120.degree. C., optionally in the presence of a small amount of catalyst, to give phase stable compositions and subsequently completely crosslinking the composition by baking the composition on a substrate. The invention also encompasses a process for painting a substrate which comprises priming the substrate with a primer selected from the group consisting of epoxy resin primers and polyester resin primers, applying to the primed substrate a crosslinkable basecoat composition comprising from 10 to 80 percent by weight of a hydroxy functional polydiene polymer having a functionality of at least 1.3, from 8 to 60 percent by weight of an amino resin crosslinking agent, and from 2 to 40 percent by weight of a reinforcing agent, and applying over the basecoat a clearcoat selected from the group consisting of dihydroxy polydiene-based clearcoats, polyester clearcoats, and acrylic clearcoats.

    摘要： Provided is a developing roll (R) with which it is possible to suppress toner stress in a low-temperature and low-humidity environment. A developing roll (R) for an electrophotographic device has a surface layer (1). In a surface hardness histogram (10) of the surface layer (1) measured by using an atomic force microscope (AFM), the surface hardness (H) at the top peak (P) is in the range of 10-55 MPa, and the area ratio (S) of the histogram portion corresponding to a surface hardness of 45 MPa or below in relation to the entire histogram is 65% or above.
