The chemisorption of cold rolling oil additives on steel and aluminium surfaces is studied with a mass spectrometry technique, ToF-SIMS. Preliminary experiments underline adsorption competition, and thermal threshold for desorption or decomposition. This results fit well with experimental cold rolling results.

A highly reliable ink jet recording head excellent in mechanical strength, weatherability, ink resistance, and adhesion to the substrate (1, 10) is provided. For its production, a cationically polymerized curing product of an epoxy resin having a structural unit expressed by the following formula (I) or (II),
is used as a resin material (5, 12) which coats an ink flow path pattern (4, 11) formed from a dissoluble resin on the substrate.

The present invention is a thermosetting silicon-containing material containing one or more of a repeating unit shown by the following general formula (Sx-1), a repeating unit shown by the following general formula (Sx-2), and a partial structure shown by the following general formula (Sx-3):
where R1 represents an iodine-containing organic group; and R2 and R3 are each independently identical to R1, a hydrogen atom, or a monovalent organic group having 1 to 30 carbon atoms. This provides: a thermosetting silicon-containing material used for forming a resist underlayer film which is capable of contributing to sensitivity enhancement of an upper layer resist while keeping LWR thereof from degrading; a composition for forming a silicon-containing resist underlayer film, the composition containing the thermosetting silicon-containing material; and a patterning process using the composition.

A thermosetting silicon-containing compound contains one or more of structural units shown by the following general formulae (Sx-1), (Sx-2), and (Sx-3):
where R1 represents a monovalent organic group containing both a phenyl group optionally having a substituent and a non-aromatic ring having 3 to 10 carbon atoms; and R2, R3 each represent the R1 or a monovalent organic group having 1 to 30 carbon atoms. Thus, the present invention provides a thermosetting silicon-containing compound usable in a silicon-containing resist underlayer film material capable of achieving contradictory properties of having both alkaline developer resistance and improved solubility in an alkaline stripping liquid containing no hydrogen peroxide.
