Abstract: [Object] To provide a positive type photosensitive composition capable of forming a cured film having high transparency [Means] The present invention provides a positive type photosensitive siloxane composition comprising: a polysiloxane, a diazonaphthoquinone derivative, an additive having a quaternary ammonium structure and the capability of interacting with the polysiloxane, and a solvent. The polysiloxane and the additive interact with each other before exposure, but they lose the interaction after exposure.
Abstract: [Subject] There is provided a gap filling composition which can reduce pattern collapse and a pattern forming method using the composition. [Solution means] There is provided a gap filling composition including a polymer having a certain structure and an organic solvent. There is provided a pattern forming method using a certain polymer.
Abstract: Temperature-stable effect pigments based on multicoated flake-form substrates, and the use thereof in paints, coatings, printing inks, plastics and in particular in glazes, enamels, ceramic or glass-like materials.
Abstract: A method for preparing a switching element which is operable in and electrically switchable between an optically clear state and a scattering state, wherein one or more polymerisable mesogenic compounds provided in a layer containing a liquid-crystalline medium which comprises one or more mesogenic compounds, one or more chiral compounds and the one or more polymerisable mesogenic compounds are subjected to polymerisation in the presence of a direct current (DC) electric field in the layer. Also, a switching element obtained or respectively obtainable by carrying out the method and to the use of the switching element in a window.
Abstract: The present invention relates to a novel styrenic polymer comprised of the repeat units of structures (I), (II), and (III), wherein R1, R2 and R3 are individually selected from H or a C-1 to C-4 linear alkyl, R5, R7 and R6 are individually selected from a C-1 to C-8 linear alkyl, a C-3 to C-8 linear alkyl and a C-3 to C-8 cyclic alkyl and to the novel composition comprised of this polymer and a spin on organic solvent. In another aspect of this invention it pertains to the use of this composition to create a grafted on a substrate, and a further aspect, this grafted film may be used in a directed self-assembly process.
Abstract: The present invention relates to spirobifluorene compounds of the formula (1) which are suitable for use in electronic devices, in particular organic electroluminescent devices, and to electronic devices which comprise these compounds.

Abstract: Environmentally stable, chemically amplified (CA) positive resist compositions are described. These resist compositions are based on a blend of at least two types of polymer platforms. The first platform is a low activation energy, acetal blocked polyhydroxystyrene (PHS) based resin; the second platform is an acrylate based resin containing a high activation energy acid labile group [such as tertiary-butyl acrylate(t-BA)]. The resist composition also contains a photo-acid generator (PAG), a base quencher, a surfactant dissolved in a suitable solvent. Also described, is the use of these resist composition in a method for forming a photoresist relief image on a substrate.
